Who is mentioned as a historical example of a saint who appeared to someone long after his supposed death?

Chapter 43 provides a powerful example to illustrate that great saints do not truly perish. It asks rhetorically, 'Did Maharaj Gyanoba (Gyaneshwar) leave?' and then explains that he gave darshan three centuries after his passing. The text specifies that Nath Maharaj was the one who met him, and this event is described as a favor done for the world. This example serves to reinforce the idea that Sai Baba, like Gyaneshwar, remains accessible and present even after leaving his physical form, transcending the conventional understanding of death.
